. Application filed March 5, 1914. Serial No. 822,746.

To all wiwmz't may concern:

'Be it known that I, Max J ACOB, a subject of the Emperor of Germany, residing at Berlin, Germany, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Slip Printing and Feeding Mechanlsm for AccountingMachines, of which I declare the following to be a full, clear, and exact description.

This invention relates to cash registers and the like and more particularly to improvements to the printing mechanism thereof.

One of the principal objects of this invention was to provide an improved slip or check feeding mechanism so that the slip or check can be fed any desired distance between printing impressions.

' In many businesses it is desirable to print a series of transactions on a printed form of slip or check, the transactions being printed by the machine on lines extending across the slip or check or beside characters or numbers. Devices for feeding printed slips or checks between printing impressions have been found satisfactory for the purpose of advancing the slip or check an invariable distance, when the same form of slip or check is to be always used or when a blank slip or check is employed, but in many cases it is desirable to change the form of the printed checks or slips and this cannot be done with these devices unless the new form of slip or check has the same space between the lines, the characters or numerals. The various users of cash registers also employ different forms of slips or checks and it is a decided advantage in the manufacture of these machines to construct the feeding -means alike for all of the machines but to provide simple adjustable means so that the extent of feed of the slips or checks can be adjusted to accommodate any form of slip This feeding mechanism in the preferred form of embodiment described herein takes the form of a movable clamping or gripping device, comprising a feeding member provided with an ad]ustable stop and carrying a pivoted gripping or To give the feeding member a feeding movement a rotation shaft is provided with a cam for cooperating with a roller on the feeding member, and a second cam is designed to operate the pivoted clamping arm during this reciprocatory nl ovement to advance the inserted check or s 1p.

Another important object of the invention is to provide a special type carrier for printing a special character on a detail strip for the purpose of designating those transactions for which no slip or check is issued.

In the illustrative form of the invention disclosed herein this object is accomplished by providing the machine with a special type carrier which is normally in position to print upon the detail strip, but is adapted to be moved out of printing position by the insertion of a slip or check. This feature of the invention may be employed to advantage in machines used in many businesses but it might be advisable to give an example here. In cafes in which patrons can obtain liquor at a bar and food and liquor at tables the same machine is often employed for registering and recording the money received both at the bar and from those who are served at the tables by waiters. For the money received at the bar no slip or check is printed but, when a waiter receives an order from patrons at one of the tables, the order is usually printed by the machine upon an inserted slip or check as well as upon the detail strip. In such a case the printing of a special character on the detail strip beside those amounts representing the money paid at the bar enables the proprietor to find out the total amount taken in from the patrons at the tables and the total amount taken in at the bar.

Of said drawings:

Figure 1 is a side elevation of the printing mechanism embodying this invention.

Fig. 2 is a front end elevation of the printing mechanism shown in Fig. 1.

Fig. 3 is a plan view of a portion of the printed detail strip, showing a special character beside one of the printed amounts for designating that a slip or check was not inserted into the machine when that transaction was entered in the machine.

In the drawings only the printing mechanism embodying the improvements is shown, it being considered unnecessary to show the printing mechanism applied to any particular type of machine as it will be evident from the description which is to follow that this mechanism can be applied to many of the well known types of machine on the market.

The amount type wheels 1, as shown in Fig. 2 of the drawings, are mounted upon the outer ends of the nested sleeves 2 and on the shaft 3 which carries the sleeves and the initial type wheel 4: is rigidly mounted upon the outermost of these sleeves. Small spacing collars 5 are provided between the type carriers and a collar 5 is provided between the units type carrier and the plate 11 of the printer frame. The shaft 3 and the sleeves 2 extend into the interior of the machine and may be differentially rotated to set up their type wheels in any desired manner, dependent upon the type of machine to which this invention is applied. Each of the amount type wheels 1,- as well as the initial type wheel 1, is provided with duplicate sets of '13 and the frame 10 of the machine to hold typearranged respectively on opposite sides of the wheel so that similar impressions may betaken from the opposite sides thereof. The detail strip 6, which may be advanced inaiiy manner from a supply roll to a receiving roll, passes under the roller 7 mounted on the forward end of an arm 8. This arm 8 is mounted on a rod 9, which is supported'at its left hand end by the frame 10 of the machine and at its right haud'end by the plate 11 of the printer frame. This roller 7 constitutes a platen and thearm 8 may be rocked downward in any desired manner to carry the roller against the upper printing line of the type wheels 1 and 4, so that a printing impression may be taken on the detail strip 6. Rigidly mounted upon a hub or sleeve 12, which surrounds the outermost sleeve 2 and is slidably mounted thereon, isa special type carrier 13 which at its upper end carries a special type 14for printing a star 15 (Fig. 3) upon the detail strip 6 beside those transactions, which are not printed upon slips or checks. A. light spring 17 is coiled about the sleeve 12 and is compressed sufficiently between the type carrier the type carrier in printing position under the detail strip 6, as shown in Fig. 2, so that when the roller 7 is lowered against the type wheels'l and 4 an impression of a star will also be taken from the special type carrier'13.

Below the type wheels is a stationary table 18 which forms a support for the inserted slip or check and the table is mounted at the side of the machine on the vertical plates or supports 19. The table is provided with a slot 20 through which operates a platen 21 which may be operated in any de sired manner to carry the inserted slip or check against the lower printing line of the type wheels 1 and 4. The arm 16 of the special type carrier 13 passes through a restricted portion of this slot to the left of the platen 21 so that this type carrier is prevented from rocking about the shaft 3. When a transaction is to be recorded upon a slip or check, as well as upon the detail strip 6, the slip or check is inserted on its table 18 in the direction of the printing line, that is, from the side of the machine. In Fig. 1 a slip or check, indicated by the reference character 23, is shown in inserted position. \Vhen the slip or check is inserted its left hand edge engages the arm 16 and slides the type carrier 13 and its sleeve 12 to the left (Fig. 3) and this movement is limited by the engagement of the end of the sleeve 12-with the bushing 24 in the frame 10 for the sleeves 2 and the shaft 3. It can be seen from this description that in this manner the special type carrier 13 is moved to the left from under the detail strip 6 by the insertion of a slip or check, so that, when the detail strip is lowered into contact with the printing line of the type carriers 1 and 4, the star will not be printed on the detail strip.

A leaf spring 25, as shown in Fig. 1, is

fastened to a vertical projection 26 (Fig. 2)

0n the left hand side of the table 18 and its free end is curved and presses against the top of the table. The slips or checks are inserted under the spring 25, the spring'being provided to revent buckling of the inserted slip or chec and also to hold the slip or check in the machine against the action of the spring 17, so that the operator may remove his fingers from the slip or check after it has been inserted. As soon as the slip or check is removed, the spring 17 returns the special type carrier 1.3 to the normal position, shown in Fig. 2, so that its special type 14 may print a star upon the detail strip if a slip or check is not inserted at the next operation of the machine.

The device for advancing an inserted slip or check is shown in Fig. 1 and will now be described. A plate 30 is provided with the slot 31 through which a rod 32 passes and the forward end of the plate is bifurcated to straddle a rotation shaft 44: so that the plate may be given a reciprocatory movement on this rod and shaft. Projecting laterally from the right hand side of a projectingportion 33 on the plate 30 and passing over the inserted slip or check is a bar 34., the lower surface of which is provided with a longitudinal notch or groove 35.

Pivoted at 36 to the plate 30 is a lever 37 also to permit its reciprocation while .it is in engagement with the bar. The forward end of the lever 37 has one end of a sprin 40 attached thereto, while the opposite end of the spring is secured to a screw eye 41.

The spring normally tends to rock the lever 37 about its pivoted center 36 but this movement is normally prevented by the engagement of the forward end of the lever with the periphery of a cam 42 which is mounted upon the rotation shaft 44. Upon movement of the shaft 44 in the direction of the arrow the cam 42 is carried away from the rear end of the lever and the spring 40 then rocks the lever 37 to elevate the beveled edge of the plate 38 into engagement with the groove 35 in the bar 34. It can readily be seen that if a slip or check has been inserted on the table 18 it will be forced by the plate 38 against the bar 34, the groove 35 being provided so that a slip or check will be gripped firmly.

After the inserted slip has been gripped in this manner, a cam 43, also rigidly mounted upon the shaft 44, cooperates with an anti-friction roller 46, mounted on the plate 30, to move the plate 30 and the lever 37 rearward against the tension of the spring 40 and in'this manner the slip or check is fed rearward so that the next line or character on the slip or check will be in printing position under the lower printing line of the type wheels 1 and 4. After the plate 30 and lever 37 have been carried rearward to advance the inserted slip or check, the cam 42 engages and rocks the lever 37 to lower the plate 38 out of gripping position with the bar 34 so that when the radial edge of the cam 48 reaches the roller 46 the spring 40 will draw the plate 30 and the lever 37 back to normal position, the slip or check being permitted to remain in its advanced position.

The rear end of the plate 30 carries a screw head 47 in which is mounted a screw 48. The head 49 of the screw is adapted to abut against and normally engage the rear support 19 for the table 18 and in this manner'it forms an adjustable stop for the plate30 and the lever 37 upon their return movement. If it is desired to feed a slip a less distance the screw is adjusted so that the plate 30 normally stands nearer the rear of the machine, so that the plate 30 will not be given as great a step of movement as before and in this way the extent of advance ment of the inserted slip or check may be regulated.

The shaft 44 may be given one rotation in any desired manner at each operation of the machine and this would usually be desired in machines in which but one printing impression is to be taken at one operation. In some cases, however, it is desirable to take a plurality of printing impressions at one operation of the machine and in such a case the shaft 44 would be given a plurality of rotations at each operation, that is, one rotation after each printing impression and it'is clear that the invention is adapted to either of these uses. It is also evident that these improvements can be employed to advantage in machines in which checks are issued from a check strip, in which 'case the special type carrier would be controlled by the check strip and the check strip would be fed by the feeding mechanism described above. It is therefore intended that the words slip or check in the claims should be broad enough to include a check strip or other record material.

lVhile the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment shown and described herein, as it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
